Yuji was currently fighting Sukuna, Choso is down currently so it's your time to help him fight Sukuna.

Sukuna was looking st some other sorcerer because of his cursed technique so he couldn't really react right now, so Yuji took advantage of that.

Yuji: Black Flash.

He then punches Sukuna with his black flash, it was massive and it caused alot of damage, Yuji had finely awakened.
